Definitions
- This invention relates to apparatus used in connection with the drilling, completion, and servicing of oil and gas wells.
- tubular goods or“tubulars” are run in these wells, including but not limited to drill pipe, smaller diameter strings commonly known as“work strings,” tubing strings, and larger diameter“casing,” drilling risers, or any tubular member. Almost all of these tubular goods are in sections or“joints,” typically on the order of 30 to 40 feet in length. The joints are typically coupled together with threaded connections. Other types of connections are used at times. All of such tubular goods will be collectively referred to at times as“tubulars.” The tubulars are coupled or connected together or“made up” into a tubular string, which ultimately are run into a wellbore.
- Tubulars are often run into a wellbore by a drilling rig having a rig floor at which the tubulars, and/or the tubular string, are landed in slips at the rig floor, as the tubulars are coupled together joint by joint to form a tubular string.
- tubular and“tubular string” is intended in its broadest manner, to include but not be limited to all of the above-mentioned tubular members.
- drift diameter for a given tubular, which may be a function of the tubular outer diameter and wall thickness.
- the drift diameter which may be referred to herein as the“drift ID,” is the minimum inner diameter (“ID”) for a tubular to have, to remain within specifications. It is important that all tubulars run into a wellbore satisfy this inner diameter specification, namely have an inner diameter of at least the drift ID and were not manufactured with a too-small inner diameter; or during transit, handling, makeup in the tubular string or for other reasons the minimum diameter was compromised.
- Verifying the inner diameter of the tubulars, in particular the drift ID, within a tubular string is important because (for example) after the tubulars are run into the wellbore, it may be required to run some sort of device down into the tubular string within the wellbore, for example a logging tool, a ball to activate a downhole tool, slickline tools, another smaller diameter tubular, etc. Since the clearances between the outer diameter of such devices and the inner diameter of the tubular in the wellbore may be very close, it is essential to verify that the drift ID of the tubular run into the wellbore is within a desired specification, or the future-run device may not be able to go downhole.
- an ID other than the specification drift ID may be desired to be verified, usually an ID slightly larger than the drift ID. In yet other cases, it may be desired to verify that an ID smaller than the drift ID is in place.
- any desired tubular ID may be referred to as a“drift ID.”
- this ID verification was done by dropping a device known as a“drift” having a known outer diameter down through the tubular, usually on the rig floor, before it was made up into tubular string and run into the wellbore.
- a“gauge ring” such device may also be referred to as a“gauge ring,” although that term is more properly applied to a device used to ensure a minimum tubular ID other than the drift ID (typically smaller than the drift ID).
- the drift may take the form of an elongated tool having a ring member with an outer diameter (“OD”) equal to or slightly smaller than the drift ID of the tubular. If the drift successfully passed through the tubular, then the inner diameter was deemed satisfactory (i.e. the minimum drift ID was verified).
- ID issues in the tubular string may be detected and resolved in a much more efficient manner.
- the apparatus for verifying inner diameter in a tubular which may be referred to as a “floating drift apparatus,” embodying the principles of the present invention comprises, fundamentally, a floating apparatus and methods of use of same in connection with tubular ID verification, as a tubular string is being run into a wellbore.
- the floating drift apparatus is typically (but not necessarily) elongated, having a desired outer diameter to verify a desired tubular ID. It is understood that the floating drift apparatus is sufficiently buoyant to float in the wellbore fluid.
- the floating drift apparatus is placed into the bore of a tubular string being run into a wellbore, where it floats in the wellbore fluid, and moves upwardly (in relative terms) through the tubular string as additional joints of tubular are made up or connected together (typically screwed together) forming the tubular string.
- the floating drift apparatus may comprise a float section and a drift section, the drift section having a drift element (such as a circular ring) with a desired diameter, which may be at or slightly less than the drift ID for a given tubular.
- the float section has sufficient buoyancy to float the apparatus in a fluid within the bore of a tubular being evaluated (that is, the inner diameter being verified).
- the drift section is positioned at or near the lower end of the float section, which may comprise an elongated flotation tube. As noted, the flotation or buoyancy from the flotation tube is sufficient to float the entire apparatus in wellbore fluid.
- the flotation tube may be 20 to 25 feet long, which is sufficient to extend from the typical fluid level in a tubular being run into a wellbore, out of the uppermost end of the uppermost tubular, which is typically 2 to 3 feet above the rig floor (with the tubular sitting in slips at the rig floor).
- the floating drift apparatus is lowered into the bore of the tubular.
- the floating drift will submerge in the wellbore fluid to an extent, but floats with a portion of the floating drift apparatus below the fluid level in the tubular and the balance extending above the fluid surface.
- the flotation tube is sufficiently long to extend to near the uppermost, open end of the uppermost tubular, and usually to extend beyond the open end by some distance, for example one foot.
- the floating drift apparatus remains in the bore of the tubular/tubular string.
- the next (e.g. the second) joint of tubular is then made up (screwed together or otherwise connected) with the first joint of tubular, and the tubular string lowered to position the second joint in the slips at the rig floor, with the open end of the now-uppermost tubular typically several feet above the rig floor.
- the floating drift apparatus is still positioned within the bore of the tubular, more-or-less floating at its same location in the fluid, as the tubular string moves downhole around it into the wellbore. It is understood that the fluid level typically remains substantially constant as the tubular string is run into the borehole. In this manner, the floating drift apparatus traverses not only the tube of the tubulars, but also the threaded (or other type of) connections between the joints.
- the floating drift apparatus typically extending out of the open end of the uppermost tubular where it can be grasped, can then be simply pulled up out of the tubular string.
- the floating drift apparatus is not at the surface after a joint of tubular has been made up, this indicates that the floating drift apparatus has lodged in a preceding tubular joint (whether in the“tube” or at a connection), due to an undersize ID being encountered; the floating drift apparatus being unable to pass through this spot to remain at the fluid surface.
- the tubular string can then immediately be lifted only one or two joints (or however many is required), the previous connections unscrewed, and the undersize ID very quickly located and identified. The undersize tubulars can then be removed and proper ones substituted.
- some means to detect the presence and/or location of the floating drift apparatus is required; alternative embodiments include a visual detection of the upper end of the floating drift apparatus; a visual detection of a light attached to the floating drift; an audio detection; measurement via sound wave echo location; or other means known in the art. Attachments such as centralizers, junk baskets, scrapers, scratchers, etc. may be added to the floating drift. A fishing neck may be added to the uppermost end of the floating drift apparatus to permit a fishing tool to latch onto the floating drift apparatus to retrieve it from the bore of the tubular string.
- the floating drift apparatus may comprise one or more rupture disks to protect against excessive fluid pressure.
- Figs. 1 - 9 are views of various embodiments of the floating drift apparatus embodying the principles of the present invention.
- Figs. 10— 12 are other embodiments of the floating drift apparatus.
- Fig. 13 is a view of another embodiment of a floating drift apparatus embodying the principles of the present invention.
- Fig. 14 is a view of the floating drift apparatus positioned within a tubular, with the tubular positioned at the rig floor and extending downwardly into the near- surface wellbore area (e.g. the fluid return equipment).
- the near- surface wellbore area e.g. the fluid return equipment
- Figs. 15 - 17 illustrate a sequence of running several joints of tubular into a wellbore, as the floating drift apparatus remains substantially in the same location, floating in the wellbore fluid.
- Fig. 18 is another embodiment of the floating drift apparatus. Description of the Presently Preferred Embodiment(s)
- Figs. 1 - 9 show various embodiments of floating drift apparatus 10 (which may be referred to at times as floating drift or drift apparatus), all embodying certain principles of the present invention.
- Floating drift apparatus 10 fundamentally comprises a body 20 having a sufficient buoyancy force to cause floating drift apparatus 10 to float in a wellbore fluid.
- Body 20 comprises a desired outer diameter, denoted in the figures as OD. It is understood that OD is selected based on what inner diameter (ID) of the tubular is sought to be verified.
- floating drift apparatus 10 further comprises one or more fluid flow passages 22, whereby fluid can flow by floating drift apparatus 10 when floating drift apparatus 10 is positioned within the bore of a tubular.
- flow passage 22 is a longitudinal bore.
- flow passages 22 are longitudinal slots positioned around the outer circumference of body 20.
- flow passages 22 are a plurality of longitudinal bores through body 20.
- FIGs. 8 and 9 show a generally dumbbell shaped body 20, with longitudinal bores through the enlarged end sections.
- FIG. 10 shows a tapered body 20 with a float section 24 and a drift section 30, and a drift element 32 of a desired OD, along with a light 70.
- Fig. 11 shows an egg-shaped body 20 with drift element 32 of a desired OD.
- Fig. 12 shows a generally spherical body 20, preferably with two drift elements 32, each of a desired OD.
- the present invention also comprises a method for verifying the inner diameter of tubulars forming a tubular string, comprising the steps of:
- floating drift apparatus 10 continuing to connect additional joints of tubulars to said tubular string and to lower the tubular string into said wellbore, floating drift apparatus 10 moving relatively upwardly through the bore of said tubular string as the tubular string is lowered into the wellbore.
- floating drift apparatus 10 comprises a buoyant float section 20 and a drift section 30.
- Float section 20 may take various forms, but in preferred embodiments is a generally elongated element.
- Drift section 30 is attached to float section 20, and comprises drift element 32 having a desired dimension, namely outer diameter (OD) as shown, which may be a circular ring with a desired OD.
- the OD of drift element 32 is equal to or slightly less than the drift ID of the tubular being evaluated (verification of ID). It is understood that the OD of drift element 32 may be any desired dimension, whether to verify a drift ID or some smaller ID.
- drift element 32 may be a complete circular or ring shape; or alternatively may be a“broken” ring (having an interrupted
- buoyancy force from float section 20 is sufficient to float the entire apparatus in wellbore fluid.
- Floating drift apparatus 10 comprises a float section 24 comprising an elongated flotation tube 25, which by way of example may be 20 to 25 feet long.
- Drift section 30, which is typically connected to a lower end of float section 24, may comprise a drift element 32 having a desired OD.
- the buoyancy from float section 24 is sufficient to float the entire apparatus in wellbore fluid.
- the length of flotation tube 25 (as noted, typically 20 to 25 feet long) is preferably sufficient to extend from the typical fluid level in the bore of the tubular in the borehole to at or above the open, upper end of the uppermost tubular joint, which is typically positioned 2 to 3 feet above the rig floor.
- flotation tube 25 may extend one foot or more out of the upper end of the tubular.
- Drift element 32 has a desired OD, typically substantially equal to the drift diameter for the tubular being run, but which may be any desired dimension; for example, the apparatus may be used to verify only a“gauge” inner diameter to ensure safe running of a tool within the tubular, which is typically a diameter smaller than the drift ID.
- Drift section 30, or drift element 32 may be interchangeable on flotation tube 25.
- Additional elements may include rupture discs 60 on flotation tube 25, and a wireline fishing neck 40 on the upper end of float section 20, to permit retrieval or“fishing” of the apparatus if needed.
- a so-called“junk basket” 50 may be added, typically to a lower part of floating drift 10.
- Rupture disk 60 permits fluid to enter the internal portion of flotation tube 25, in the event that floating drift apparatus 10 is subjected to high pressures due to being placed at a greater-than-expected depth in the wellbore fluid, for whatever reason. This feature avoids collapse of flotation tube 25.
- Fig. 14 shows floating drift apparatus 10 positioned inside the bore of a tubular which is positioned at the surface, typically in slips in the rig floor, noted in the figure.
- Various other components of the general setting are also shown in Fig. 14, including an exemplary fluid level within the bore of tubular string 100.
- Figs. 15-17 illustrate a sequence of running tubulars into a borehole with floating drift 10 in place. Certain elements shown in Fig. 14 are omitted for clarity.
- Fig. 15 illustrates an exemplary starting point of running the tubular string.
- a first joint of tubular (labeled tubular joint #1) is in place, typically in slips in the rotary. It is understood that multiple joints of tubular are joined or connected together (e.g. by threaded connections) to form a tubular string.
- the fluid level inside tubular joint #1 is shown, with floating drift 10 floating in the fluid.
- the lowermost end of the tubular is shown with connection #1 shown (which may take various forms; the notation of connection #1 is primarily for reference purposes).
- tubular joint #1 is above the rig floor, and the uppermost end of floating drift apparatus 10 may extend beyond (out of) the uppermost end of tubular joint #1.
- fishing neck 40 is omitted for clarity.
- Fig. 16 illustrates the next joint of tubular, joint #2, being run into the wellbore. It is understood that joint #2 has been coupled together or connected with joint #1 at connection #2. The fluid level remains more or less constant. The position of floating drift apparatus 10, relative to the rig floor, also remains more or less constant, as the joints of tubular are run downhole around floating drift apparatus 10.
- Fig. 16 illustrates drift section 30, and more particularly drift element 32, passing through connection #2. It can be understood that in the position shown in Fig. 16, drift element 32 has passed through joint #1, is passing through connection #2, and will be passing through joint #2 (i.e. the tube thereof), thereby verifying the proper ID of those tubulars and the connections between them.
- Fig. 16 shows joint #2 in place in slips at the rig floor.
- the uppermost end of floating drift apparatus 10 is extending beyond the uppermost end of joint #2, thereby verifying that drift section 30/drift element 32 has passed through joint #1 and connection #2, and at least a portion of joint #2.
- floating drift apparatus 10 comprises some means to allow an operator to detect or verify the presence/location of floating drift apparatus 10 within the tubular.
- the means for detecting or verifying the location of floating drift apparatus 10 is a simple visual one, by the operator seeing floating drift 10, whether or not floating drift apparatus 10 extends out of the uppermost end of the tubular.
- Other means for detecting the location of floating drift apparatus 10 include an indicator light 70, see Figs. 10, 11 and 18 as examples.
- Indicator light 70 may be a battery powered light known in the relevant field.
- floating apparatus drift 10 comprises an indicator light 70 at its uppermost end.
- Still further optional/supplemental means for detecting the presence of floating drift apparatus 10 include electronic devices, e.g. Wifi, RFID or similar devices, denoted generally as 80.
- Still other means may include echo location, denoted schematically as 90.
- Floating drift apparatus 10 may further comprise centralizer 120, a junk basket 50; or wire scrapers/scratchers, denoted generally as 130; and/or a magnet.
- Materials for floating drift apparatus 10 are commonly known in the relevant industry, including high strength steel, non-ferrous, non-metallic seal elements if required, etc. Methods of manufacturing would include those commonly used for similar apparatus.
- FIG. 10 shows an embodiment in which float section 20 is generally disposed below drift element 30, when the apparatus is in place within the bore of a tubular.
- An indicator light 70 which may be battery powered, may be disposed on floating drift 10 and positioned so as to be visible from above. An operator can then visually detect the location of floating drift 10 even though floating drift apparatus 10 does not extend out of the tubular string. With this embodiment, retrieval of floating drift 10 may be by a magnet or other means.
- float section 20 is a generally oblong shape on which drift section 30, including drift element 32, is connected.
- floating drift apparatus 10 generally takes the form of a sphere having a desired diameter.
- float section 20 and drift section 30 are effectively merged into one, comprising one or more drift elements 32 so as to provide the drift ID verification regardless of orientation of floating drift 10 within the bore of the tubular.
